PAVEMENT.

Specification of Letters fatent. PatentdDefl, 20, 1910 Application filed October 26, 1908. Serial No. 459,522-

To all whom it may concern:

Be it known that I, MATTHEW E. DUN n,

of the city, county, and State of New York, have invented certain new and useful Imof which the. following is a full, clear, and exact specifica- I tion, such as will enable others skilled in the {tart towhich it appertains-to make and use the same.

My invention relates to a pavement useful on streets and roadways of all sorts but particularly intended to be laid on streets over which there is heavy trucking traflic, and the object of the invention is primarily to provide an, indestructible pavement ca- .pable of sustaining the heaviest loads and affording a secure foothold for horses and a good traction surface for motor driven vehicles.

I attain this end by certain novel features which'will be fully set forth hereinafter and particularly pointed out in the claims.

The accompanying drawings represent, as an example, one of the various fornis into which the principles of my invention may be practically embodied and in-these drawings, Figure '1 is a plan view of the pavement; Fig". 2 is a vertical section thereof; and Fig. 3 is -an enlarged vertical section clearly illustrating the manner of tying together the reinforce sections. 3

, In constructing the pavement' a suitable bed,or foundation is laid as indicated at a in Figs. 2 and 3. The nature of this foundation or bed is entirely immaterial excepting that it should be sutliciently strong to carry the weight of the pavement and its superimposed load.

- The pavement is constructed of a suitable paving material laidlastic and allowed to harden and reinforce with iron. The pave- ,ment material employed for this purpose may be varied to suit the conditions to be met. For heavy traffic, however, I prefer to employ ordinary concrete. In the drawings terial which is laid plastic and allowed to harden in the usual manner.

c'indicates the reinforce sections which are entirely separate from each other and other metallic materiaLand, accordingto the form of the invention illustrated, in the drawings, .these sections are rectangular in dg'est on edge on the foundation or t bed a; the upper edges of the sections c be ing exposed above the surface or me paving material Z) to furnish a foothold for horses and an eifective traction surface for motor to the shape of the reinforce sections which a continuous skeleton or net-like frame or reinforce. The sections may be secured together by various devices but I prefer the ties d shown best in Fig. 3. Said ties have laterally bent ends cl forming hooks which reinforce sections 0 and ,after the concrete or other paving material hardens around them they form a firm rigid connection between the reinforce sections.

The pavement thus constructed is of the lm ostdurable character. The concrete or other paving material cannot crack because it is divided into numerous small bodies by the reinforce sections and should any one of these bodies become injured at any time it may be readily broken out independently of the remainder of the pavement and a new section laid in its place. If a section of the pavement is to be taken up for repair or for sewers under the street this may be readily done by removing as many of the reinforce sections a and connections d as may be required and after the necessary perfectly both in appearance and structure with the remainder of the pavement.

Having thus described my invention, what ters Patentof the United States is:

l. A continuous street pavement having sections placed on.edge on the foundation and spaced from each other, said reinforce sections having openings in the walls there- 'of, metallic ties extending between the adjacent walls ofadjacent reinforce sections and provided at their ends with beads, said ends inner surfaces of said sections to prevent separation thereof and being removable through said openings, thereby joining the reinforce sections together and ermitting any one of them to be removed wlthout dismaterial laid on the foundation and between the reinforce sections.

driven vehicles. 1 am not limited, however,.

work is completed the section of the. pavement-removed may be relaid and will'match I claim as new and desire to secure by Letturbing the others, and a sheet of paving.

may be in various forms. flhese reinforce sections 0 are fastened together so as to form are introduced through openings-o in the" a foundation, a number of metallic reinforce projectingthrough said openings and said heads being adapted to contact with the 2. A. continuous street pavement having a foundation, a number of metallic reinforce sections placed sideby-side, but spaced from each other and placed on edge on the foundation, said reinforce sections having openings therein, short, r gid, one-piece metallic maeee nether and permitting any one of them to be removed without disturbing the others, and a sheet of paving material laid on the foundation and between the reinforce sections, the upper surface of such paving material lying in a plane adjacent to the upper edges of the reinforce sections.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
